Great Site ...
Hi Larry ... good to hear from you, too! I've reached out a couple of times about that website to individuals who were struggling to find parts, advice, etc. The last time, a person posted here about an N2L; surprised that no one responded. Oh well!
I've watched some YouTube videos on people using these machines and just cringe at the abuse! The biggest issue is not enough water and then overloading. Those machines were meant to be used with a full tub of water and not be overloaded. Instructions were/are pretty clear. That's probably what happened to yours; it was overloaded so much in its previous life that when you got it, it had already suffered damage to the gears. Those are lifetime gears; pretty hard to bust.
You are also right that it was easier for Maytag service people to send wringer heads and power units back to Maytag to be rebuilt and replace them with either new or used. Replacing the gears in the PU is tricky and the thrust adjustment is really difficult to do. Same thing with rebuilding the wringer head gears; I've only done it a couple of times and it was so, so difficult! The Maytag plant had all the right tools and equipment to quickly rebuild.
I bought a whole replacement wringer for a Model E/J from Cottage Craft Works; I couldn't be more happy! Expensive, but it was worth it to me. Wrings really tightly and I haven't taken the cap off to see what they did; doesn't appear to have oversized roller holders but I do notice a large washer on the lower roller to the right next to the drain pan cam.
Amish people still use wringer washers exclusively and the supplier to Cottage Craft Works is selling quality parts; especially the drain hoses and seals. Pretty impressive. Glad they are there and hope they keep doing it! They also have a lot of other cool things. Reminds me of Lehman's Hardware, but Lehman's has a lot more items. Still great, though.
Take care ... Happy 4th!!
